Bro-sum if your vehicle requires premium 91-92; I'd be mixing 87 & e85 all day w/prices soaring skyhigh! You'll get proper octane readings of approx. 91-95 w/a ½ & ½ mix for those high comp. bangers bro!😆👌"erryone's doing it man, save a penny dude"

The fuel level sensor, I’ve replaced a few already so don’t worry abt forgetting the name, I call the budget maker

I have a 19 Gallon fuel Tank I use 5 gallons E85 14 Gallons 93 the I can Royal Purple Octane boost. All stock 2015 Taurus Ecoboost. Passed e-check no issues and runs great.

I was just thinking of doing this to my Taurus. With it being my daily I’ve been debating on it.

[@Chiefgeargrinder]

@stephenprice9635 I do it to keep octane to 100. Don't go over 5 Gallons. Most gas has 10% already.
